I've run into this several times, and I have yet to see this addressed here (although I haven't looked very hard). Occasionally upb doesn't work off the edge, and what happens is that both Popo and Nana perform a solo IC upb move, even though they're right next to each other. I was just wondering if anyone had ran into this problem. It just seems like a major blow to an already gimpable recovery if you're forced to midair jump/dodge before executing upb.
